CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 327,301, datedSeptember 29, 1885.

Application filed December 4, 1884. (No model.)

To all whom it may concern:

Be it known that I, NELsoN NEWMAN, of

Springfield,in the county of Sangamon, and in the State of Illinois,have invented certain new and useful Improvements in Corn-Planters,

and Ido hereby declare that the following is a full, clear, and'exactdescription thereof, reference being had to the accompanying drawings,

in which- Figure 1 is a perspective view of my apparatus, the seed-boxand dropping mechanism being removed. Fig. 2 is a plan view of the upperside of the-same. Fig. 3 is a like view of the lower side of saidapparatus, the full and dotted lines showing different positions of theaxles. Fig. 4 is a side elevation of the S3316, and Fig. 5 is anelevation of its front en i Letters of like name and kind refer to likeparts in each of the figures.

The design of my invention is to enable corn to be accurately planted inintersecting rows without the use of the ordinary check-row line, and tothis end said invention consists, principally, as an improvement incorn-planters, in the combination of three or more ground-wheels, whichare geared together to rotate in the same time, with dropping mechanismthat is actuated by said wheels, substantially as and for thepurposehereinafter specifie'd. 1

It consists, further, in the combination of two axles, which are gearedtogether and caused to revolve in the same time, three or moreground-wheels,that are connected with and adapted to rotate said axles,and seed-dropping mechanism which is actuated by the same, substantiallyas and for the purpose hereinafter shown a It consists, further, incombining with axles, which are driven by three or more groundwheels, anendless chain that connects said axles together and causes the same torotate in the same time, and also actuates the seeddropping mechanism,substantially as and for the purpose hereinafter set forth.

It consists, further, in the combination of two axles, which areconnected together so as to rotate in the same time and are adapted toactuate seed-dropping mechanism, with ground-wheels that are journaledupon said axles and may be connected with or disconnected from the sameby shiftable clutches, substantially as and for the purpose hereinaftershown and described.

It consists, finally, in the means employed for connecting thechain-operated lever with the seed-slides, substantially as and for thepurpose hereinafter set forth.

In the annexed drawings, A designates the center bar, and B and B theside bars, of the platform of my apparatus, which bars are connectedtogether at their ends by means of two cross-bars, G and O, as shown.

Pivoted at the longitudinal center of each cross-bar O is an n -shapedmetal bar, D,

which at each end is provided with a box, d, within which is journaledan axle, E, that in turn has journaled upon each of its ends a groundwheel, F, said wheels, axles, and frame-bars thus combined constitutinga rolling support for the platform.

Each wheel F is connected with its axle E by means of a clutch, G, whichis placed upon and caused to revolve with said axle, while capable ofsliding lengthwise of the same, and has its outer toothed end, 9, heldin engagement with the toothed inner face of the hub f of said wheel bymeans of a spring, H, which is placed between the inner end of saidclutch and the outer end of the contiguous journalbox 01.

Each clutch G is withdrawn from engagement with its wheel by means of abar, I, which has its upper end pivoted within a fixed support, K, andits lower forked end 2' arranged to embrace said clutch outside of aperipheral collar, 9. A cord or chain, L, having its lower end attachedto or near thelower end of said bar I, passes from thence through anopening, d, in the vertical portion of the adjacent frame-bar D, andfrom thence to and around a vertical bar, M, at or near the center ofthe platform, furnishing a means whereby said bar I may be moved inward,such movement, together with a simultaneous movement moved rearward,carry in the same direction of the other bars I, being caused by thepartial rotation of said bar M, so as to wind around it said cords.

The axles E are connected together, so as to simultaneously move inopposite directions upon their pivotal bearings, by means of two rods,N, each of which is pivoted at one end to a rearward extension of one ofthe journalboxes d, and from thence extends diagonally across and hasits opposite end pivoted to the box 01 of the other axle upon theopposite side of the machine. As thus connected, the movements of thefront axle in turning the machine produce correspondingly-oppositemovements of the rear axle, so as to cause the wheels to follow in thesame tracks, and to enable said machine to be turned in a much lessspace than would otherwise be required.

At the longitudinal center of each axle E is secured a chain-wheel, 0,around which and around the similar wheel 0 of the opposite axle passesa chain, 1?, that operates to connect said axles together and cause themto revolve in precisely the same time without regard to their relativeangles. At suitableequidistant points upon said chain are placed washersp, which, as the latter moves longitudinally, engage with the lowerforked end q of a lever, Q, that is pivoted vertically within thecentral bar, A, of the platform at the transverse and longitudinalcenter of the same.

As stated, the lower end q of the bar Q is forked, and spans the chainP; but as the space between the forks is less than the diameters of thewashers 12 each of thelatter as it moves forward engages with and movessaid forked end in the same direction until, from the move- .ment ofsaid bar upon its pivotal bearing,said

forked endv is raised sufficiently to permit said washer to pass frombeneath, after which, by means of a spring, said bar is caused to resumeits normal position again.

The upper projecting end, q, of the bar Q is connected with theseed-dropping mechanism, so that at each rearward movement of said upperend said dropping mechanism is caused to act and .deposit the desiredquantity of seed within the ground. Any form of connection which willaccomplish the result may be employed; but I preferably use a bar, R,which has its central portion made thin transversely, so as to form aspring, 1", is pivoted midway between said spring portion and each end,and has its ends connected with the droppingslides.

By this arrangement the end q will, as it is the central portion of saidspringbar and cause its ends to be simultaneously moved forward,whileupon the release of said operati ngbar Q from engagement with a washer,p, said spring-bar will automatically return to its normal position andcarry with it said seedslides and operating-bar.

Runners S for opening furrows are located upon each side of the machine,between the wheels F, and are attached to and supported by a bar, T,which extends laterally across the platform and serves, also, to supportthe seed-boxes and dropping mechanism. In order that said runners mayb'eremoved from contact with the ground when not in use, the projectingportion at each end of said bar T is hinged and capable of being'turnedupward and inward to the position shown in Fig. 5. As the space betweenthe upper ends of said runner is greater than the necessary width ofsaid cross-bar, the rear portion only of said runner is secured to thelatter, and this front portion ishinged to or upon an arm, U,w,hich

projects laterally outward from the platform. Having thus described myinventiomwhat I claim is e 1. In a corn -planter, the combination ofthree or more ground-wheels,which are geared together to rotate in thesame time with dropping mechanism that is actuated by said wheels,substantially as and for the. purpose specified.

2. In a corn planter in which are two axles that are geared together andcaused to revolve in the same time, the combination therewith of threeor more ground-wheels, which are connected with and adapted to rotatesaid axles, and seed dropping mechanism that is actuated by the same,substantially as and for the purpose shown.

8. In a corn-planter in which the axles are driven by three or moreground-wheels, in combination therewith an endless chain. that connectssaid axles together and causes them to revolve in the same time, andalso actuates the seed-dropping mechanism, substantially as and for thepurpose set forth.

4. In a corn-planter, the combination of two axles, which are connectedtogether so as to rotate in .the sametime and are adapted to actuate theseed-dropping mechanism, with ground-wheels thatare journaled upon saidaxles and may be connected with or discon-i nected from the same by.shiftable clutches, substantially as and forthe purpose shown anddescribed.

5. In combination with the vertically-pivoted operating-lever adapted tobe vibrated by the continuously-moving knotted chain, the bar R,provided with the spring central portion, 1", and pivoted between saidportion and each end, and having its ends connected with theseed-dropping slides, substantially as and for the purpose set forth. Ir

In testimony that I claim the foregoing I have hereunto set my hand this24th day of October, 1884.

NELSON NEWMAN.
